NORFOLK, Va. (AP) - About 600 concrete balls will be placed into the Lafayette River this summer to help restore the oyster population.

The Chesapeake Bay Foundation said in statement that it used a crane last week to lower 100 of the balls into the water in Norfolk.

The Lafayette is a tributary of the Elizabeth River, which flows into the Chesapeake Bay. The nearly 5-acre (2-hectare) reef is being constructed at the mouth of the Lafayette.

ANNAPOLIS, Md. (AP) - Reef balls are being planted on the Tilghman Reef this week.

The Coastal Conservation Association Maryland and the group's northern Virginia chapter is scheduled to plant 140 reef balls west of Tilghman Island in Talbot County on Wednesday.

The association says the reef balls will triple the size of the existing reef, making it one of the largest man-made, three-dimensional reefs in the middle of Maryland's portion of the Chesapeake Bay.

NORFOLK, Va. (AP) - The Chesapeake Bay Foundation has lowered 25 concrete oyster reef balls into the Lafayette River in Norfolk.

Oyster harvesting has been banned on the Lafayette since the 1920s because of contamination from industries and storm water runoff. The work Tuesday is part of an initiative to restore the Lafayette to health.

Reef balls are dome-shaped concrete structures that provide a surface on which swimming oyster larvae can attach. Balls are seeded with live baby oysters called "spat." They also provide the benefit of shoreline stabilization.
